We present a method of direct measurement of spectral gain and corresponding data in photonic crystal waveguides defined in heterostructures on InP substrates. The method makes use of two… (More)
Experimental results on wavelength-dependent angular dispersion in InGaAsP triangular lattice planar photonic crystals are presented. An abrupt variation of the angular dispersion is observed for… (More)
Electrical spectrum line-width is reduced in mode-locked FP 1.55 μm-QD laser diode through optical confinement factor optimization. From optimized structures, we obtained nearly Fourier-transform… (More)
Lasing of triangular and square lattice photonic crystal, waveguides on InP substrate is investigated around the 1.5-/spl mu/m wavelength by optical pumping. The lattice period of the fabricated… (More)
Polarisation insensitive injection locking of two-section Fabry-Perot laser diodes is demonstrated, allowing to achieve error free transmission through 50 km over 20 nm at 2.5 Gb/s.
More than 120 nm of -3 dB optical bandwidth, together with 10 dB of internal gain at 50°C, are demonstrated and explained with specially designed quantum dot semiconductor optical amplifiers.
The effect of p-doping on both temperature and dynamic performances of 1.55µm Quantum Dashes lasers is investigated in detail. A relaxation frequency up to 13.5GHz and a damping factor as low as… (More)
A modulation bandwidth up to 10 GHz in continuous wave mode operation is demonstrated using optimized 1.55 mum InAs/InP (100) quantum dashes based lasers.
We demonstrate that the combination of Quantum Dots and Quantum Dashes (QD) structures with buried ridge stripe technology allows to achieve QD semiconductor amplifier (SOA) with an internal gain of… (More)
Single mode lasing of square lattice photonic crystal (PhC) waveguides is investigated experimentally and compared to simulation results. Lasing of a Wl PhC waveguide structure at 1.5 /spl mu/m on… (More)
